Be it known that we, A..GAAR and D. M. COOHBAN, of Richmond, Wayne connty,State of it Indiana, have in'vented certain Improvements in Machines forElevating and Stacking Straw; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in 'which---- t Figure l is an elevation of .our stacker arranged for operation. Fi g. 2 shows the stacker folded up. Fig. 3 is alongitudinal section through Fig. 1. Fig. 4 shows the mannerof pivotingthe elevator to the frame of the thrash- Fig. 5 shows one of the flanged tubular bearin gs for pivoting the elevating contrivances tothe thrashcr. Fig. 6 is a perspective view, showing the manner of connecting the upper hinged section of the elevator to itslower section. Fig. 7 is a modification of tion of the elevator.

Sim lar letters of reference indicate correspending, parts in the'several figures.

The main object of this invention is to conthe guards at the upper end'of the upper secduct straw fromthe straw-carrier and chafi" from the riddle of a thrashing-machine to a suitable height to deliver it in stacks by means of a machine which will protect the straw during its upward movement from the influence of wind, and whichcan be folded up so as to occupy very little space when not in immedi-* ate use or during transportation.

Another object of our invention is to provide for elevating or depressing the highest end of an elevator which employs endless belts and folding sections without the necessity-of changing or adjusting the length of the driving-belts of stacker to accommodate them. to the change of position. a

Another object of our invention is to provlde for directing. the straw downward upon the stack when the former reaches its highest peint by means of an adjustable guard and a hinged apron, which latter also protects the falling be hereinafter described.

To enable others skilled inthe art to'understand our invention, we will describe its construction and operation. a

of the required width, connected together and braced in lines parallel to each other by means of the transverse bars a a. The width of this frame is equal to the width of the boxA', which .is formed by the side-boards at the rear end of the thrasher, and the length of this frame or sectionis equal to the-distance from the ver- 'tical post B to the extreme rear end of the box A',.as shown in Figs. 1, 2, and 3. I

The upper section, b b, of the elevator-frame is constructed and braced substantially as .above described for the low er section, a, and

if other sections are required for giving greater height to the upper end of the elevator, they will be constructed as described. The two sections 1) b are hinged together at c by means of hinges whose leaves 0 c are nearly, it notquite.

equal in width to that of the side-boards to which they are secured. The hinge or point ofmovement is located at the lower edges of said frame-sections, so' that the upper section. may be folded under the lower section, as represented in Fig. 2. When the sections D b are in a right'line with each other they are secured in this position by means of a hook, :1, having a notch cut into it,,which receives the lugs d d.- that are formed on the upperedges of the hinges, as shown in Figs. 1 and 6. The-lugs d d may be perforated,as shown Fig. 6,to receive bolts for making a more rigid fastening. On both sides of both sections of the elevator-frame are guard-boards c e, which project. up so as to form fenders or guards, to prevent the straw in its upward passagefrom fallingoft' the machine at such points, and also to prevent the strawv from being blown of! at the sideot' the machine.

F F are horizontal shafts, which are arranged D represents one section of the elevatorframe, which consists of two sideboards, a a,

at ornear theextremities of the elevator-frames, as shown in Fig. 3,for the purpose of receiving and keeping taut the bands g g of the endless straw-elevator. ranged near the ends of the drums or shafts F F, and provided with slats arranged transversely across the frames which sustain said shafts and secured to the belts, as shown in Fig. 4.

Any form of endless apron which will-ele vate straw, may be stretched over the drums F F and used instead of the one shown.

In a plane touching the upper points of the drums 1" F are secured boards G G, which are used to prevent the straw or chaff from falling through the elevator during its upward movement over these boards.

The lower end of the lower section of olevator-fran'le is connected by tubular bearings h h to the vertical posts of the box or housing A, as shown in Fig. 4. These tubular bearings are formed with a screw portion, 1!, on each,-and also flanges h", as shown in Fig. 5, and they are screwed into the sides of the section a, so that their hearing portions can be supported so as to oscillate freely in boxes applied to the posts 13. Through these tubular bearings and through the axis of the drum 1" passes a rod, 6, which is afiixed to, so as to turn, this drum, and on one end of the rod-i a beltwheel is affixed, over which a belt passes that gives motion to the straw-elevator.

It will be seen from the above description that the frame or sections of frame are pivoted at the lower end to the thrasher-frame by short bearings, through the axis of which passes the shaft'which rotates the drum F; hence the axis of motion of the elevator-frame and the lower drum which carries the belts of the elevator are in common, and any adjustment of the upper end of the elevator-frame in a vertical plane lwllll not affect the tightness of the drivinge t.

The lower edges of the housing-boards of the rear end of the thrasher incline, as shown in Figs. 1, 2, and 3, so that the highest degree of elevation desired may be given to the elevator. A rod, j, passes transversely beneath the elevator, and has its support in the inclined beams B B of the housing A. When it is required to lower the upper end of the elevator the rod j is removed and inserted into lower holes of the beams B. When the .upper end of the elevator is depressed there would be left an opening between its lower section and t e lower inclined edges of the box A, through which the straw and'chaif would be blown out Of the machine. To guard against this the J S de-boards e, which are secured to the frame of "section D, fill up said openings when the elevatoris depressed.

These bands or belts are ar At'the upper end of the upper section of the elevator is a defleetor,.H,whieh is open at its bottom: and top, but closed at its sides and To the lower edge of the deflector an apron,

H is hinged for the purpose of preventing the wind from blowing'the fallin g chaff and straw about. The deflector and-its hinged apronmay be made of light boards, or they may be made of thin sheet metal. The deflector is hinged or pivoted at p to the upper end of the upper section of the elevator, as shown in Figs. 1 and '3, so that the deflector, with its apron, may be turned up in the'position shown in Fig. 2 when the elevator is folded up The deflector-plate may be secured to the side-boards of the upper section, b, by extending said arms beyond the upper drum, as shown in Fig. 7. In this case the apron only is hinged.

Having thus described our invention, what we claim as new, and desire to secure by Lethanging posts or beams BV and rod j, when these are used for confining and supporting the' stacker in transportation or in operation, substantially as herein described.

2. The combination of the guard or side boards 0 of the section D with an adjustable stacker and the box A of a thrashing-machine, substantially as described.

3. A hinged or pivoted deflector,H, applied at the'diseharging end of-the stacker, substantially as described. 4. The hinged apron H, in combination with aeontriva nee for protecting the straw from the wind at its point of discharge from the stacker,-. substantially as described.

5. A folding sectional stacker which is susceptible of being elevated or depressed without leaving wind-openings at theside of the lowest section, and which is arranged and combined with the rear end of a thrashingmachine in such manner that it can be folded beneath the same, substantially as described.-
